Research of ZnMn spinel electrode material for aqueous secondary batteries

ZnMn complex oxides have been prepared by the organic acid complex method. X-ray diffraction (XRD) analyses show that the major product is a ZnMn spinel phase. The capacity of the sample is above 200 mAh g −1 on cycling in aqueous LiOH electrolyte, but deep-discharge has great influence on the cyc...

Description
Summary:ZnMn complex oxides have been prepared by the organic acid complex method. X-ray diffraction (XRD) analyses show that the major product is a ZnMn spinel phase. The capacity of the sample is above 200 mAh g −1 on cycling in aqueous LiOH electrolyte, but deep-discharge has great influence on the cycling property of the sample. XRD analysis shows that Li + ions are intercalated into and extracted from the ZnMn spinel lattice during the discharge and charge process.
